Sawdust 4L bag x 3 used for growing wood loving mushrooms like Shiitake
Can be used in the PF Tek also with Brown Rice flour instead of the mixture below
The best method for mixing:
100 parts hardwood sawdust
10 parts Wheat Bran
1 part gypsum (calcium sulphate)
Water until moist and well soaked through. Drain or squeeze out excess water. The substrate should be damp but not wet. Pack into autoclavable bags and sterilized from 1-4 hours at 15 psi depending on the volume of the substrate. Larger volumes need a longer sterilization time to heat the core enough for complete sterilization. Depending on the type of bag and method of inoculation, the bags can be sealed before or after sterilization.
